As with other games that are re-released later, I think that it might already include the patches so that you don't have to download and install them. Are you experiencing any issues with the game now? If not, you shouldn't worry about it.

I have looked up Syberia DJC publisher, and it's Encore. You can find here their support section dedicated to Syberia 1 & 2 DJC, but there is no mention whatsoever of a patch. So I am guessing there isn't one available.

If you are running Vista, make sure you install and run the game in Administrative Mode. Also select "Windows XP" compatibility in the game's shortcut. In addition, try updating your video card drivers to check if that wall problem is resolved. You can also update your DirectX here. Alternatively, you could try running the game on another computer to see if the issue persists.
